White blood cells
White blood cells are a major hematopoietic cell along with red blood cells and platelets. These cells do not contain hemoglobin, but they contain a nucleus. The number of white blood cells in normal cases ranges from about 4,000 to about 10,000 per millimeter of blood. The leukocyte count is usually examined as part of blood tests to diagnose diseases when there is a high temperature and if inflammation is present in a part of the body.
The function of these cells is to defend the body against pathogens, bacteria, microbes that attack the body, or any abnormal cells in the human body, and the number of these cells indicates the existence of diseases; in the case of attacking the body by the factors of disease, the number of these pellets rises significantly.
White blood cells are formed within the bone marrow, lymphatic tissue, liver, and spleen. The white blood cells are short; they range from several hours to two days in some cells. White blood cells are divided into two types: granular cells, and granular cells, and can be identified by their appearance under the microscope.
Diseases that cause white blood cells increase
The high number of white blood cells usually indicates one of the following:
- Increased production of white blood cells to fight inflammation.
- The body’s reaction to drugs that increase the white blood cell counts.
- Bone marrow disease causes abnormal growth of white blood cells.
- Defective immune system that leads to increased production of white blood cells.
Causes of high white blood cells
Some causes of high white blood count include:
- Lymphatic leukemia.
- Acute myeloid leukemia (AML).
- Allergies, and especially severe allergic reactions.
- Chronic lymphocytic leukemia.
- Chronic renal leukemia.
- Medicines, such as steroids, adrenaline.
- Bacterial or viral infections.
- Pure fibrosis.
- Vera red.
- Rheumatoid Arthritis.
- Smoking.
- Stress, such as severe psychological or physical stress.
- tuberculosis.
- Whooping cough.
- Aesthetic anemia.
- Tissue damage due to burning.
- Pregnancy.
- Sensitivity.
- asthma.
Symptoms of increased leukocyte count
There are no specific symptoms of high white blood cell count, as these symptoms vary according to the disease causing them. These are some examples:
- High temperature.
- Increase the rate of bleeding.
- Feeling tired and tired.
- Gastrointestinal pain.
- breathing difficulties.
- Weak vision and vision.
- Loss of appetite, leading to weight loss.
Function of white blood cells
The function of the first white blood cells is to defend the body against the factors that cause diseases, and these cells fight alien objects and eliminate them, and die some white cells during the defense of the body, and some white blood cells secretion of histamine that causes the widening of blood vessels that lead To the occurrence of allergies in the body.
These cells also secrete heparin, which has a major effect in preventing blood clotting. Some types of white blood cells act on amoeba and many other bacteria, thus contributing to healing of wounds and tissues. These cells primarily work on antibody formation, Plasma cells, white blood cells containing substances that analyze lipids, and also produce hormone-stimulating thyroid work. White blood cells have a distinctive defense method when the body is attacked by various pathogens.
White cell types
There are several classifications of white blood cells, the most important three main types, and these categories include:
- Loving , Divided into three types:
- Neutrophils.
- Eosinophils.
- Fencing.
- The Unit , And develops two types:
- Dendritic cells.
- Pharyngeal cells.
- Lymphocytes , Divided into two types:
- B cell cells.
- T cell cells.
